To all 107mm t may concern.'

Be it known that I, JsTUs J. Ross, a-citizenl of' United States,residing at Huntington, in the county of Cabell and State of IVestVirginia, have invented certain new and useful Improvements in lifletalMine Ties, of which the following is a full, clear, and exactdescription.

The invention relates to metal mine ties 1"," and one of'the objects ofthe invention is to provide a device of this character which isinexpensive in manufacture, and yet which possesses sufficient strengthand durability 'to withstand theV severe usage to which it is subjectedjAnother object' ofthe invention isto provide a tie which will securelyclamp rails of various sizes without altering the gauge of the track.

material part of the present application is to provide a novelanchoringr means by which movement of the tie invany direction isprevented.

Further objects and advantagesk of the invention will be apparent from`the following detailed description whentaken inconnection with theaccompanying drawings; in which, 30, Figure 1 is an elevational viewVofthetie,

parts beingin section, and showing a section of a large railclamped inposition, and also showing a small rail in dotted outline.

Figure 2 is a fragmentary plan view of the tie with a rail in position,an

Figure 3 is a detail perspective view of a portion of the tie with theanchoring means detached.

Referring to the drawings more in detail, numeral l indicates the bodyof the tie, which has a fiat top surface and downwardly extendingflanges 2 on each side thereof; that is, the body of the tie has thecross-sectional shape of channel iron. These flanges possess a dualfunction, in that they add considerable strength to the tie and at thesame time they act as an anchoring means to prevent any lateral movementof the tie.

The ends of the tie are turned upwardly and inwardly to form hook shapedends as indicated by numeral 3; and wooden wedges 4C are insertedbetween the hooked ends and the rails to force the latter into place.

A novel form of clamping lug is indicated Another object of theinvention forminga by numeraly 5. The specific `form of the clamping lugforms the subject-matter of a separate application, but itsconstruction` and operation will be briefly described herein. In Figurel, I have shown in section relatively large rails clamped in position.and in dotted outline is shown a smallrail clamped in position. Railsare composed'of three parts, the head, the web, and the flange, andthese partsare indicated by thenumer-l als 6, 7, and. 8,respectively'forthe large rails; andby. numerals 6', 77 and 8,respectively, for the small rails. The clamping lug 5 has a-flatportion-9 coinciding Vwitlithe flat surface of the tie, and anupwardlyinclined portion 10 for engaging the flange of the rail or theweb of the rail as the casev may be, depending on the sizeof the rrailein?y ployed. The clamping lug is prov-ided with: strengthening sideflanges l1, and theA lug is.

preferably secured to the tie byy means of! rivets.

The clamping lug-5 is soL designed: that when it is employed with thelargest rails commonly'used in minework, it will follow the contourof'thef rail iange or baseA 8, and thus exactlyA fix the positionl ofthe largest rails, as'clearly illustrated in'Figure'l. It will be noted,however, thatthe lug does not extend up to the web of the railwhen thelarger rail is employed. If the inclinedfpo-rtion of the clamping luglextendedl up to the web when large rails were employed, then it wouldbe obvious that when smaller rails were employed the inclined portionwould also strike the web and hold both the small and large rails in thesame position, thus altering the gauge of the track. On the other hand,if the inclined portion was so designed that it was much shorter thanillustrated herein, then when a small rail was used, its iiange would beforced under the lug until it contacted with the inclined portion at thepoint where the lug meets' the surface of the tie, and consequentlythere would be considerable variation in the gauge. The clamping lug isnot so designed, however, and by an inspection of Figure 1 it will beseen that when a small rail is em-` ployed the web 7 abuts against thefree end of the inclined member, and when a large rail is employed theweb does not contact with the inclined member at all, but the flange ofthe larger rail contacts with the inclined member at the point where thelug meets the surface of the tie. By this construction the verticalcenter line of the'rail is moved only slightly `for different sizerails, andtliis difference in position just about compensates' for thedifference in width of the heads of different size rails, so that thegauge remains almost exactly the same. 1

As previously mentioned herein, the side flanges 2, 2, of the tie body,in addition to strengthening the tie, also serve as an anchoring meanstoprevent lateral displacement.y One of the material features of thepresent invention is 4to provide additional means to preventlongitudinal displacement of the ities. Attached to the tie, preferablybelow each ofthe rails, is a. novel form of anchoring means, asindicated by numeral l2. rIhe anchoring means comprises a shortnietalstrip having a flat surface 13 adapted to coincide with the bottomof thetie, and downwardly extending side flanges 14 adapted to dig into theground or mine floor and prevent longitudinal movement of the tie. Itwill be noted that the flanges 14, 14; of the anchoring means are ofgreater length thanlthe flanges 2, 2 of the tie body, so that theflanges 14;, 14, will first dig into the mine floor, and will befollowed by the flanges 2, 2. It will also be noted that the channeliron section constituting the longitudinal anchoring means is preferablyyof a length equal to the distance between vthe flanges 2, 2 of the tie.It is apparent that if the member 12 extends from flange to flange ofthe tie, that it will be easily and securely held in place, for it isobvious that any rotation of the anchoring means would be impossibleeven ifonly one rivet should be employed. v v l vIt isbelieved that theconstruction and have described what I now believe to be the bestembodiment of the invention, but I do not wish to be understood therebyas limiting myself oi the scope of the invention, as many changes andmodifications may be made without departing from the spirit of theinvention; allsuch I aim to include in the scope of the appended claims.

rHaving fully described the invention, what I claim as new and desire tosecure by Letters Patent is: l

l. A metal cross tie, the body of said tie having the cross-sectionalshape of channel iron, anchoring means attached to the bottom of thetie, said anchoring means having the cross-sectional shape of channeliron.

2. A metal cross tie, the body of said tie having the cross-sectionalshape of lchannel iron, anchoring means attached to the bottom of thetie, said anchoring means having the cross-sectional shape of channeliron, and said anchoring means Vextending below the bottom of .said tie.

A .metal cross tie, longitudinally extending down-turned flanges on saidtie, hooked ends formedon said tie, rail clamping lugs mounted on thetie, wooden wedges adapted to be inserted between the rails and i thehooked ends of the tie, anchoring means extending between the downturnedflanges, said anchoring means having the cross-sectional shapeof channeliron and the downwardly extending flanges thereof beingl greater depththan the first-mentioned flanges and arranged substantially at rightangles thereto.V 1
